1) Verifying that the pressure drop across the combined HEPA filters and charcoal adsorber banks is less than or equal to 4.7 inches W.G. while operating the system at a flow rate of 6500 cfm 110Z.

2) Verifying that the heaters dissipate 37 1 3 kW when tested in accordance with ANSI N510-1975.

e. After each complete or partial replacement of a HEPA filter bank, by verifying that the cleanup system satisfies the in-place penetration and bypass leakage testing acceptance criteria of less than II in accordance with ANSI N510-1975 (however Prerequisite Testing, Section 8 and 9 shall be in accordance with ANSI N510-1980) for a DOP test aerosol while operating the system at a flow rate of 6500 cfm 110Z and

f. After each complete or partial replacement of a charcoal adsorber bank, by verifying that the cleanup system satisfies the in-place penetration and bypass leakage testing acceptance criteria of less than 0.05Z in accordance with ANSI N510-1975 (however Prerequisite Testing, Sections 8 and 9 shall be in accordance with ANSI N510-1980) for halogenated hydrocardon refrigerant test gas while operating the system at a flow rate of 6500 cfm 110Z.

g. At_least once per 18 months by:

1. Verifying that on a Fuel Building Exhaust Gaseous Radioactivity-High test signal, the system automatically starts (unless already operating) and directs _its exhaust flow through the HEPA filters and charcoal adsorber banks and isolates the normal fuel building exhaust flow to the auxiliary / fuel building exhaust fans-

2. Verifying that the system maintains the Fuel Building at a negative pressure of greater than or equal to 1/4 inches W.G.

The minimum water depth is consistent with she assumptions of the safety analysis.

3/4.9.12 SPENT FUEL ASSEMBLY STORAGE The restrictions placed on spent fuel assemblies stored in Region 2 of the spent fuel pool ensure-inadvertent criticality will not occur.

3/4.9.13 DERGENCY EXHAUST SYSTEM - FUEL BUILDING The limitations on the Emergency Exhaust System ensure that all radioactive material released from an irradiated fuel assembly will be filtered through the HEPA filters and charcoal adsorber prior to discharge to the atmosphere. Operation of the system with the heaters operating to maintain low humidity with automatic control for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the adsorbers and HEPA filters. The OPERABILITY of this system and the resulting iodine removal capacity -are consistent with the assumptions of the safety analyses. ANSI N510-1975 and N510-1980 will be used as procedural guides for surveillance testing.

3/4.7.7 EMERGENCY m AUST SYSTEM - AUXILIARY BUILDING The OPERABILITY of the Emergency Exhaust System ensures that radioactive materials leaking from the ECCS equipment within the Auxiliary Building following a LOCA are filtered prior to reaching the environment. Operation of the system with the heaters operating to maintain low humidity using automatic control for at least 10 continuous hours in a 31-day period is sufficient to reduce the buildup of moisture on the charcoal adsorbers and HEPA filters.

The operation of this system and the resultant effect on offsite dosage calculations was assumed in the safety analyses. ANSI N510-1975 and N510 -

1980 will be used as procedural guides for surveillance testing. The surveillance requirements associated with the HEPA filter, charcoal adsorbers and heaters are stated in 4.9.13.
